Neon Serverless Skill

Configures the Neon Serverless Driver for optimal performance in serverless and edge computing environments.

When to Use

• Setting up connections for edge functions (Vercel Edge, Cloudflare Workers)
• Configuring serverless APIs (AWS Lambda, Google Cloud Functions)
• Optimizing for low-latency database access
• Implementing connection pooling for high-throughput apps

Not recommended for: Complex multi-statement transactions (use WebSocket Pool), persistent servers (use native PostgreSQL drivers), or offline-first applications.

Code Generation Rules

When generating TypeScript/JavaScript code:

• BEFORE generating import statements, check tsconfig.json for path aliases (compilerOptions.paths)
• If path aliases exist (e.g., "@/": ["./src/"]), use them (e.g., import { x } from '@/lib/utils')
• If NO path aliases exist or unsure, ALWAYS use relative imports (e.g., import { x } from '../../../lib/utils')
• Verify imports match the project's configuration
• Default to relative imports - they always work regardless of configuration

Reference Documentation

Primary Resource: See [neon-serverless.mdc](https://raw.githubusercontent.com/neondatabase-labs/ai-rules/main/neon-serverless.mdc) in project root for comprehensive guidelines including:

• Installation and compatibility requirements
• HTTP vs WebSocket adapter selection
• Connection pooling strategies
• Query optimization patterns
• Error handling and troubleshooting

Quick Setup

Installation

npm install @neondatabase/serverless

Connection Patterns

HTTP Client (recommended for edge/serverless):

import { neon } from '@neondatabase/serverless';
const sql = neon(process.env.DATABASE_URL!);
const rows = await sql`SELECT * FROM users WHERE id = ${userId}`;

WebSocket Pool (for Node.js long-lived connections):

import { Pool } from '@neondatabase/serverless';
const pool = new Pool({ connectionString: process.env.DATABASE_URL! });
const result = await pool.query('SELECT * FROM users WHERE id = $1', [userId]);

See templates/ for complete examples:

• templates/http-connection.ts - HTTP client setup
• templates/websocket-pool.ts - WebSocket pool configuration

Validation

Use scripts/validate-connection.ts to test your database connection before deployment.
